ecu anomaly

Is an Astra like a LeCar? If so, it only has 3 plug leads! s

sparks dont come from the ECU, they come from an ignition coil. If this car has direct ignition, then one of the coils could be bad. or a plug could be bad, or a wire.

Late German cars like the Opel Astra probably has 1 transistor per coil. As I noticed on some late model like the BMW which has four coil packs, each of which is directly driven by a sigal transistor from inside the computer.

The solution is easy. Swap the coil and if the plug that you've mention is now getting spark then, WALLA, you've found your problem. So how do I know if it has spark? Simple. Use a timing gun because the voltage is too high to fool around using the old fashioned way of "screw driver on plug wire."
